To all whom it may concern:

Be it known that I, C IHIRO'N KAIZUMI, of Tokyo, Japan, a subject of-Idis Majesty the Mikado of'Japan', have invented new and useful Improvements inRolling Stamps, of which the following is a specification.

' This inventionirelates to improvementsin revolving hand-stampsofthe type in .which a double faced stamp-body is used and an inking pad is ..inoorporated in. the handle.

The object of the invention is to provide' such stamp which is durable and simple in construction and perfect in operation. According to my lnvention, an improved means is provided for turning the stamp-body and: for holding it normally in the vertical posltion.

Annexed drawings illustrate my invention,'in which v Figure 1 is a longitudinal section of th stamp according to my invention.

Fig. 2 is an end view thereof. Figs. 3 and 4e are front views of the essential parts of the invention, Fig. 4 showing the stamp-body assuming the position in which it is pressed on the article to be stamped, and dotted lines in Fig. 3 showing such stamp-body in partially revolved position.

Similar reference numerals refer to similar parts throughout the drawings.

Referring to the drawings, 1 is a handle of any convenient form and of the. desired length and is provided at its lower end with an ordinary inking pad 2. On one side of the handle 1 is a box 3 containing a spiral spring 5. Located diametrically opposite to the said box 3 and pivoted to the handle 1 in any suitable manner is a supporting spring 4, of which the extremity is hooked as at a. 6 is a stamp supporting rod, one end of which is bent at right angles to form a shaft Z) for the'stamp body. At the other end said rod 6 is formed with a head or sliding member 0 which is located within the box 3 and bears against the lower end of the spiral spring 5.

The stamp body 7 is provided with a radial hole for receiving the shaft 7), i. e., the

of a ring 8 screwed to the body. Secured to or made integral with the stamp body is an elongated hexagonal block or. ear 6 ridge or. high portion iisFfOrmed, such high portlonixbelng, lower than the edge ofthe concav1ty,-as shown. in- Fig. 1 From the drawing itwill be seen that'thehOQk a of; the springf' l normally bears -against the inner edge of theqconcavityfof the earat one passingthe high portion z'inthe concavity" of the ear and assuming the position 5 in the box 3 being compressed by' Specificatioirof Ihetter sfP atntJ 5; Application files-Se tember 4, 1919. f a'a1ivo.321,%33.@ e

v formed withaconcavity, in

shown in .At this time the upper face: of the stamp body-is pressed against the inking pad soon ashandle l is raised, the said hookfaw1ll slide along the lower inclined "edge of r in the usual manner."

the'ridge z' and will come to the right hand corner (in Fig. 4),orangle of the lower triangle and, asthe. point of support is thus transversely shifted from the axisof rotation of the stamp. body as shown, in dotted lines in Fig. 3, the stamp body will be turned by the action of the spring 5. Then it is prevented from overturningjand isheld in verticalposition-by the hook a; ofthe spring 4,

as shown in full linesin Fig. 3. In the manner described, the stamping operation can be continuously effected.

What I claim is I 1. In a stamp of the type referred to, the

combination with a stamp jbody rotatably' supported, of a supporting rod bent at one end at right angles to form a shaft for the stamp-body and at the other end bearing" against a spiral spring contained in a box attached to the handle, an ear secured to or made integral with the stamp body and pro-' vided with a concavity in which a ridge or high portion is obliquely arranged, and a supporting spring formed at its extremity with a hooked portion normally engaging the uppermost inner edge of the said concavity.

2. In a stamp of the type referred to, the combination with a stamp body rotatably supported, of a supporting rod bent at one.

end at right angles to form a shaft for the H stamp body and at the other end bearing against a spiral springcontained in a box attached to the handle, an ear secured to-or porting spring formed at its extremity with a hooked portion normally engaging the uppermost inner edge'of the said concavity, theiarrangement being such that when the handle is pressedagalnst the article to be stamped, the hook ofthe'supportin-g spring will passthe ridge in the concavity.

3. In'a stamp of thetype referred to, the combination with aistamp body rotatably supported, of a supporting rod bent at one end at right angles to form a shaft forithe stamp body and at the othervend bearing againstla spiral spring containedin a box vided with a concavity in which a ridge or 7 high portion is obliquely arranged, and a supporting spring formed at its extremity with a hooked portion normally engaging the uppermost inner.-.edgeof the said conunderside of: the ridge is guided along the; inclined edge thereof, whereby the point or by the action of said spiral-spring.

support is shifted transversely from the axis of rotation of the stamp body and the'latter .thus turned half a revolution about itsaxis 2o attached tothe handle, an ear secured to or made integral with the stamp body and pro-
